The actress, who's often called the first female superstar of Indian cinema, died of a cardiac arrest in Dubai on Saturday. Celebrities from the film industries have been expressing their grief and shock at the news.

Rishi Kapoor, who has worked with Sridevi in films like Chandni, Nagina and Banjaran, changed his Twitter profile picture to black, as a mark of respect. "Sridevi, RIP," he wrote in his bio.

Sridevi died in Dubai on Saturday, after a cardiac arrest. She had gone to attend actor Mohit Marwah's wedding ceremony festivities.

According to a report in Khaleej Times, Sridevi was getting ready for a dinner date with husband Boney Kapoor when the tragedy occurred. A source close to the Kapoor family is quoted as telling the publication that Boney flew down to Dubai from Mumbai and went to Sridevi's room at the Jumeirah Emirates Towers Hotel at around 5.30pm to surprise her. They had a brief conversation before he asked her to have dinner with him.

Sridevi went to the washroom to freshen up. When fifteen minutes passed, Boney knocked on the door but received no response. He then forced open the door and was shocked to find her lying motionless in the bathtub filled with water. "He tried to revive her and when he could not, he called a friend of his. After that, he informed the police at 9pm," the insider said.

Paramedics tried to resuscitate her, but she was already dead. Her body was then taken for autopsy to the General Department of Forensic Medicine.

Sources from the General Department of Forensic Medicine told India Today, "Late on Sunday night, some blood samples of actress Sridevi were sent for tests." The reports are expected to come by 10am Dubai time (11.30am IST), and are crucial to clear the body for transportation.

After this, a death certificate will be issued and the body will be taken for embalming. It appears that the family will be able to collect her mortal remains only by late afternoon, after which they will bring it back in a private jet to Mumbai.

Sridevi is survived by her husband, Boney Kapoor, and two daughters, Khushi and Jahnvi Kapoor.
